The essential oil of Rosa damascena petals was evaluated for its antibacterial effects against three strains of Xanthomonas axonopodis spp. vesicatoria. The essential oil may be a potential control agent in the management of the disease caused by X.a. vesicatoria in tomato and pepper plants.
Rosa damascena mill L., known as Gole Mohammadi in is one of the most important species of Rosaceae family flowers. R. damascena is an ornamental plant and beside perfuming effect, several pharmacological properties including anti-HIV, antibacterial, antioxidant, antitussive, hypnotic, antidiabetic,
Antioxidant and antibacterial potential of different solvent extracts of locally grown Hibiscus rosa-sinensis Linn was evaluated. The antioxidant activity was assessed by estimation of total flavonoids contents, total phenolic contents, DPPH free radical scavenging activity and percentage inhibition
The effects of pulverized petal of Rosa rugosa on the growth of 10 species of intestinal and pathogenic bacteria were investigated. Growth of bifidobacteria and lactobacilli was not affected by the addition of the petal in plate cultivation. However, the growth of Bacteroides vulgatus, Escherichia
A new isoflavone derivative was isolated from Rosa damascena by using various chromatographic techniques including silica gel, Sephadex LH-20, and preparative RP-HPLC separation. Its structure was identified as 4'-hydroxy-7-(3-hydroxypropanoyl)-6-methoxy-isoflavone using combined examinations of
The aim of the present study was to determine the antioxidant and antimicrobial properties in freeze-dried extracts of rose fruits (Rosa rugosa) obtained using various extraction techniques and to determine the effect of a selected extract on bacterial survival in model fluids imitating
Hibiscus rosa sinensis, a member of the Malvaceae family, is widely cultivated in the tropics as an ornamental plant. It is often planted as a fence or hedge plant, and has several forms of flowers with varying colours. It is also used in traditional medicine to induce abortion, ease menstrual
OBJECTIVE
To access the in vitro antibacterial activity of Hibiscus rosa-sinensis (H. rosa- sinensis) flower extract against human pathogens.
METHODS
Antibacterial activity was evaluated by using disc and agar diffusion methods. The protein was run through poly acrylmide gel electrophoresis to view
In the present study, biosynthesis of silver nanoparticles was carried out using Rosa chinensis flower extract as reducing agent. The characterization of silver nanoparticles was done by UV-VIS spectrum. The morphology and size of silver nanoparticles were determined by transmission electron
OBJECTIVE
To study the anti-inflammatory and antibacterial effects of different processed products of Rosa laevigata root and stem.
METHODS
Different processed products were obtained from Rosa laevigata root and stem by frying with vinegar,salt,honey and black bean juice. Their antibacterial effect
Aim and Introduction: Rosa damascena is one of the most well-known species of the Rosaceae family and is widely used in the food and perfume industry. Rose hydrosol is a product which is produced by distillation of rose petals. There is very little research about the antimicrobial
Rugosa rose provides one of the largest hips frequently used in the preparation of pharmaceutical and food products. The aim of work was to conduct multidirectional study of biological activity and chemical composition of Rosa rugosa hips. Antiradical, cytotoxic (against cervical and breast cancer
In biomedical applications, silver nanoparticles (Ag NPs) are of great interest due to their cost-effective and environmentally friendly properties. Green synthesis of nanoparticles for biological research is a preferred choice since it does not require additional reducing agent. For this purpose,
The present study was aimed at biosynthesis of silver nanoparticles (AgNPs) using ethanolic extract of rose (Rosa indica) petals and testing their potential antibacterial activity using selective human pathogenic microbes, anticancer activity using human colon adenocarcinoma cancer cell line HCT 15
The root of Rosa roxburghii Tratt (Ci Li Gen) is a kind of Chinese ethnomedicine in Gui Zhou province, used for the treatment of abdominal pain, acute bacillary dysentery, gastroenteritis and other diseases in human and livestock.The aim of this study was
